Wrong. Not only you are missing EXISTING functionality in AmiBroker,
but also you have misconception about risks of looking into the future.
It is highest time to (re-)read the docs.

> I CANNOT use:
YES YOU CAN.
You should use expandFirst if you want values for current week without delay.
TimeFrameSet(inWeekly);
RSI_Weekly = RSI(14);
TimeFrameRestore();
RSI_Weekly_on_Daily_chart = TimeFrameExpand(RSI_Weekly, inWeekly, expandFirst);
> Taking values from an incomplete bar has nothing to do with going into the future.
Yes it does. Because the "last" value you see using that method in REAL LIFE
in Monday, Tuesday, Wednesday and Thursday will be different from LAST value you see in backtest.
The last value visible on chart will change for all four first days of the week and may generate
generate signals that will "disappear" on Friday because of future price movement
that is UKNOWN on Monday and Tuesday, Wednesday, Thursday.
This classic future leak. Period.
